The case of Daniel Billings was on Monday adjourned for a fortnight, more than 18 months after he was charged with the domestic violence-related murder of Ms Ticehurst in the NSW town of Forbes.
It was the latest in a string of delays, amid lengthy legal negotiations spanning many months.
The case has not progressed to the Supreme Court and Billings is yet to enter pleas, more than 500 days after Ms Ticehurst was found dead in her home in the early hours of April 22, 2024.
Legal Aid solicitor Diane Elston told Forbes Local Court the case was still not ready to proceed because she was unable to have a final face-to-face session with Billings, who is in the supermax wing at Goulburn jail.
Industrial action by Corrective Services NSW officers on Thursday had interfered with a planned meeting at the state's highest-security prison to go over legal documents, the court was told.
Outside court, Ms Ticehurst's father Tony fought back tears while describing the heartache caused by the ongoing wait.
"I wish to express my disappointment, yet another delay in Molly's case," Mr Ticehurst told reporters.
"It seems to me that in life, the system let Molly down and in death continues the same route.
"Instead of getting closure, all we get is anxiety, sadness and heartache."
Mr Ticehurst said he had been in touch with local MP Philip Donato, who offered to raise concerns about the delays with the state's attorney-general.
Attorney-General Michael Daley declined to comment while the case was before the courts.
Mr Donato said he would inform Mr Daley of the string of adjournments, while acknowledging politicians cannot influence the courts.
"It's important that (the attorney-general) be aware of what's going on, especially in this particular matter because it was such a high-profile case," Mr Donato told AAP.
Billings, Ms Ticehurst's former boyfriend, had been freed on bail by a local court registrar a fortnight before the alleged murder despite being charged with several counts of raping the 28-year-old and other violent offences.
Police had taken out an interim apprehended violence order against Billings on Ms Ticehurst's behalf.
He is accused of breaching the order on the night of the alleged murder.
The circumstances of Ms Ticehurst's death intensified a national campaign against domestic and gendered violence.
The movement sparked changes to NSW laws, including stripping registrars of the power to grant bail, "show cause" thresholds for domestic violence-related bail applications and electronic monitoring for accused people.
Billings is facing 17 charges, including aggravated sexual assault, several counts of stalking and intimidation and property damage.
A fresh charge of animal cruelty, related to Ms Ticehurst's puppy, was laid on October 27.
Magistrate Michael Maher adjourned the matter to November 14.
